Full Multiscale Approach for Optimal Control of In Situ Bioremediation
(American Society of Civil Engineers, 2004)Solving field-scale optimal groundwater remediation design problems is a challenge, especially when computationally intensive reactive transport models are needed. In this paper, a full multiscale approach to partial ... -
Optimal Hedging and Carryover Storage Value
(American Society of Civil Engineers, 2004)Properties of optimal hedging for water supply releases from reservoirs are developed and discussed. The fundamental decision of how much water to release for beneficial use and retain for potential future use is examined ... -
Effects of Climate and Dam Operations on Reservoir Thermal Structure
(American Society of Civil Engineers, 2004)Recently, the United States Bureau of Reclamation agreed to increase spring releases from Upper Colorado River Basin reservoirs to create a more natural flow regime in the lower Gunnison River and Upper Colorado River. ... -
Groundwater Monitoring Network Optimization with Redundancy Reduction
(American Society of Civil Engineers, 2004)Three optimization models are proposed to select the best subset of stations from a large groundwater monitoring network: (1) one that maximizes spatial accuracy; (2) one that minimizes temporal redundancy; and (3) a model ... -
Multiobjective Genetic Algorithms for Design of Water Distribution Networks
(American Society of Civil Engineers, 2004)This paper presents a multiobjective genetic algorithm approach to the design of a water distribution network. The objectives considered are minimization of the network cost and maximization of a reliability measure. In ... -
Genetic Algorithms for Reliability-Based Optimization of Water Distribution Systems
(American Society of Civil Engineers, 2004)A new approach for reliability-based optimization of water distribution networks is presented. The approach links a genetic algorithm (GA) as the optimization tool with the first-order reliability method (FORM) for estimating ... -
Interior Floodplain Flood-Damage Reduction Study
(American Society of Civil Engineers, 2004)Evaluation of flood risk in an interior watershed (one protected from flooding by a levee) requires application of watershed, channel, statistical, and economic models in an integrated, coordinated manner. The Strong Ranch ... -
Effects of Design Practice for Flood Control and Best Management Practices on the Flow-Frequency Curve
(American Society of Civil Engineers, 2004)Peak-flow attenuation is widely used in urban storm-water systems. Standard practice typically involves peak shaving of postdevelopment flows to predevelopment peak-flow levels for given return interval storms. In most ... -
Striking the Balance: Long-Term Groundwater Monitoring Design for Conflicting Objectives
(American Society of Civil Engineers, 2004)This study demonstrates the use of high-order Pareto optimization (i.e., optimizing a system for more than two objectives) on a long-term monitoring (LTM) application. The LTM application combines quantile kriging and the ... -
Multiobjective Sampling Design for Water Distribution Model Calibration
(American Society of Civil Engineers, 2003)Sampling design (SD) for water distribution systems (WDS) is undoubtedly an important issue, and has been addressed in the past by a number of scientists and practitioners. The aim of the SD methodology developed here is ... -
Closure to “Predicting Chlorine Residuals in Drinking Water: Second Order Model” by Robert M. Clark and Mano Sivaganesan

Estimation of Urban Imperviousness and its Impacts on Storm Water Systems
(American Society of Civil Engineers, 2003)Imperviousness is an important indicator of the impact of urbanization on storm water systems. A hydrologic analysis was performed to evaluate long-term impacts from an apartment area in Miami. The result shows that the ... -
Hybrid Approach for Modeling Wet Weather Response in Wastewater Systems
(American Society of Civil Engineers, 2003)This paper presents a hybrid modeling approach for modeling flows within wastewater pipe networks. The approach utilizes the MOUSE model as a deterministic pipe network model and a radial basis function neural network ... -
Optimal Measurement Site Locations for Inverse Transient Analysis in Pipe Networks
(American Society of Civil Engineers, 2003)The quality of leak detection and quantification and calibration for friction coefficients in pipelines and networks by the inverse transient method are dependent on the quantity and location of data measurement sites. ... -

Controlling Storm-Water Runoff with Tradable Allowances for Impervious Surfaces
(American Society of Civil Engineers, 2003)Storm-water flow from an impervious surface can lead to stream degradation, habitat alteration, low base flows, and increased toxic loadings from nonpoint sources, a problem that has resisted traditional command and control ... -

Reservoir Simulations of Synthetic Rain Floods for the Sacramento and San Joaquin River Basins
(American Society of Civil Engineers, 2003)In response to the destructive floods of 1983, 1986, 1995, and 1997, the U.S. Army Corps of Engineers and the Reclamation Board of the State of California are partnering a study to investigate flood damage reduction and ... -
Improved Process for Floodplain Delineation from Digital Terrain Models
(American Society of Civil Engineers, 2003)Flooding is a hazard with serious socioeconomic consequences for all activities and infrastructure within an affected floodplain. Accurate delineation of flood extents and depths within the floodplain is essential for flood ... -
Evaluation of Neural Networks for Modeling Nitrate Concentrations in Rivers
(American Society of Civil Engineers, 2003)Artificial neural networks (ANNs) are applied to estimating nitrate concentrations in a typical Midwestern river, i.e., the Upper Sangamon River in Illinois. Throughout the Midwestern United States, nitrate in raw water ...
